The spectrum of BPS branes on a noncompact Calabi-Yau
We begin the study of the spectrum of BPS branes and its variation on lines of marginal stability on OIP2(−3), a Calabi-Yau ALE space asymptotic to C/Z3. We show how to get the complete spectrum near the large volume limit and near the orbifold point, and find a striking similarity between the descriptions of holomorphic bundles and BPS branes in these two limits. We use these results to develo...
متن کاملBPS mass spectrum from D-brane action
We derive the BPS mass formulae of the Dirichlet branes from the Born-Infeld type action. BPS saturation is realized when the brane has the minimal volume while keeping the appropriate winding numbers. We apply the idea to two cases, type IIA superstring compactified on T 4 and K3. The result is consistent with the string duality, and the expected spectrum for the BPS states is reproduced.
متن کاملBPS spectrum of Argyres-Douglas theory via spectral network
We study the BPS spectrum of four-dimensional N = 2 superconformal field theory of Argyres-Douglas type, obtained via twisted compactification of six-dimensional AN−1 (2, 0) theory on a sphere with an irregular puncture, by using spectral networks. We give strong evidence of the equivalence of N = 2 superconformal field theories from sixdimensional theories of different ranks by systematically ...
متن کاملBPS Spectrum of the Five-Brane and Black Hole Entropy
We propose a formulation of 11-dimensional M-theory in terms of five-branes with closed strings on their world-volume. We use this description to construct the complete spectrum of BPS states in compactifications to six and five dimensions. We compute the degeneracy for fixed charge and find it to be in accordance with U-duality (which in our formulation is manifest in six dimensions) and the s...
متن کاملSplit attractor flows and the spectrum of BPS D-branes on the Quintic
We investigate the spectrum of type IIA BPS D-branes on the quintic from a four dimensional supergravity perspective and the associated split attractor flow picture. We obtain some very concrete properties of the (quantum corrected) spectrum, mainly based on an extensive numerical analysis, and to a lesser extent on exact results in the large radius approximation. We predict the presence and ab...
